The primary goal of this study was to evaluate the effects of different irrigation and fertilization regimes on the growth and yield of soybean across various soil types. The study found that irrigation and fertilization significantly influenced soybean growth and yield. Optimal fertilization levels, particularly nitrogen, phosphorus, and potassium, were crucial for maximizing yield in arid regions under drip irrigation. Supplemental irrigation during the reproductive stage significantly improved growth and yield in temperate humid climates. Different irrigation regimes also showed varied impacts on yield and water productivity, with partial irrigation proving most effective in semi-dry conditions. Additionally, nitrogen and iron fertilization in Mediterranean-type soils enhanced growth and yield, with a notable interaction between the two nutrients. Soil type played a critical role, with sandy loam soils benefiting most from frequent irrigation. Soil compaction, irrigation, and nitrogenous fertilization collectively influenced vegetative and physiological characteristics, with proper management mitigating negative impacts. The study also highlighted the importance of irrigation intervals and combined soil and foliar fertilization for optimal yield and quality. The findings underscore the importance of tailored irrigation and fertilization strategies to enhance soybean growth and yield across different soil types. Effective management practices, including optimal fertilization and irrigation scheduling, are essential for maximizing productivity and ensuring sustainable soybean cultivation.
